Notes •white dwarf, neutron star, black hole Neutron star- collapsed to radius of 10-15km fluid center solid surface Sugar sized cube would be 100 million tons Can’t be more massive then 2-3Msun Hot, spin rapidly, and strong magnetic fields Prevents own heat escaping Collapse and rotate faster Magnetic fields frozen into them Pulsar Neutron stars only star small enough to be pulsar Found in supernova remnants Periodic flashing in linked to rotation not pulsation Light house theory creating electric field around itself 10^5 times more then the suns radiation Converts rotational energy Crust 10^16 times more rigid then steel Superconductors “Star quake” rotation increases, crust breaks, shrink 1 to 2 mm Formation Stars 8-20Msun form neutron star At first spins close to 100x a second Move at a high velocity

Unformatted text preview: Asymmetrical explosion Supernova explosion in binary system could blast apart Gravity waves Wobble/gravitational red shift/electromagnetic signal time delay/light time delay Black Holes Collapsing star more then 2-3Msun no known force can stop it Degenerate neutrons and electrons can’t support force 0 radius infinite density and gravity Rs=2GM/c^2 G=gravitational constant M= mass c= speed of light Special effects of black holes Gravity is extreme only at the approach of it Fall at time dilation same for you slow for everyone else Tidal forces crush you and stretch you longitudally Heat up to millions of degrees Search for Black Holes Look for X-ray and Gamma rays OTHER Hypernovae or collapsar What happens when 20+Msun collapses into a black hole...
